The Howl of a Protest campaign were a series of peaceful protests in New Zealand which occurred on the 16 July 2021. The protests were organised by the farming advocacy group Groundswell NZ in opposition to the Government's new and proposed freshwater regulations, winter grazing rules, indigenous biodiversity regulations, and vehicle emissions feebate scheme (known by the group as the "Ute tax"). The scheme was particularly contentious among farmers, tradepersons and the agricultural sector since it proposed adding a fee up to $5,000 on motor vehicles with high tailpipe emissions in order to fund electric vehicle subsidies.
